摘要:

目的 探究利妥昔单抗一线治疗框架下,大包块滤泡性淋巴瘤(FL)的特征及预后。 方法 回顾性研究2009年9月至2021年9月之间收治的525例初治使用利妥昔单抗作为一线治疗药物的FL患者[342例使用利妥昔单抗联合化疗(R-chemo),183例使用利妥昔单抗联来那度胺(R2)],分析大包块FL患者的临床病理特征、基因突变以及预后。 结果 大包块FL患者相较于非大包块FL患者,淋巴结累及区域≥ 5、结外器官受累数目≥ 2个、骨髓累及、LDH升、FLIPI1高危组、FLIPI2高危组的比例显著升高。ZNF608在大包块FL患者中的突变率显著高于非大包块FL患者。使用R-chemo作为一线治疗方案的情况下,大包块FL患者与非大包块FL患者的PFS和OS无统计学差异。使用R2作为一线治疗方案的情况下,大包块FL患者的PFS和OS显著缩短。 结论 大包块FL患者相较于非大包块患者,基线时多项高危因素的比例显著升高。初治时大包块FL患者的无化疗方案需在R2基础上进一步探索。

Abstract:

Objective To explore the characteristics and prognosis of follicular lymphoma (FL) with bulky disease under rituximab-based first-line treatment. Methods A retrospective analysis was conducted on 525 FL patients diagnosed between September 2009 and September 2021 who received rituximab as a first-line treatment [342 patients received rituximab combined with chemotherapy (R-chemo), 183 patients received rituximab plus lenalidomide (R2)]. The clinicopathologic characteristics, gene mutations, and prognosis of bulky FL patients were analyzed. Results Compared to non-bulky FL patients, bulky FL patients had a significantly higher proportion of lymph node ≥ 5 sites, ≥2 extranodal involvement, bone marrow involvement, elevated LDH, and a higher proportion in the high-risk group of FLIPI1 and FLIPI2. Gene sequencing revealed a significantly higher mutation rate of ZNF608 in bulky FL patients compared to non-bulky FL patients. In patients receiving R-chemo as the first-line treatment, there was no significant difference in progression-free survival (PFS) and overall survival (OS) between bulky and non-bulky FL patients. However, in patients treated with R2, the PFS and OS of bulky FL patients was significantly shorter. Conclusions Bulky FL patients compared to non-bulky FL patients have a significantly higher proportion of high-risk baseline characteristics. For bulky FL at diagnosis, chemo-free regimens require further exploration on the basis of R2.
